Product Overview
The Subaru Fluorocarbon Water Pipe O‑Ring set is engineered for durability and precision. Crafted from premium fluorocarbon (FKM) material, each O‑ring offers exceptional resistance to high temperatures up to -40°C, oil, fuel, and coolant chemicals. The set includes two genuine OEM‑specified O‑rings (part number 806933010) that match Subaru’s exact tolerances, ensuring a perfect seal in the water crossover pipe of the transmission system. With a compact package measuring 2.95 x 2.05 x 0.55 inches and a lightweight design of 0.634 ounces per piece, the set is convenient for both professional mechanics and DIY enthusiasts.
Usage
These O‑rings are intended for the water crossover pipe in Subaru models ranging from 1993 to 2019, including the Baja, BRZ, Crosstrek, Forester, Impreza, WRX, WRX STI, Legacy, and Outback. They are ideal for routine maintenance, transmission overhauls, or repair of coolant leaks. Install the O‑rings when the pipe is removed, clean the sealing surfaces, and press the new rings into place to restore a leak‑free system. The fluorocarbon composition tolerates the extreme temperature swings typical in Subaru engines, making it suitable for both cold‑climate and high‑performance driving conditions.
